After the clone troopers won the initial assault and drove back the Umbaran militia, they set up an encampment on the nearby ridge to rest. However, several Umbaran militia members managed to sneak behind them, including this one which released a Millicreepassassin droid that started attacking and killing the clone troopers. Shortly after, the Umbarans opened fire, but all of them were eventually killed after Jedi MasterPong Krell called in an airstrike on the ridge.
